At the _Observation Pavilion_ she was described as constrained, staring fixedly into space, mute, requiring to be dressed and fed. _Under Observation:_ 1. For five months the patient presented a marked stupor. She was for the most part very inactive, totally mute, staring vacantly, often not even blinking, so that for a time the conjunctivæ were dry. She did not swallow, but held her saliva; did not react to pin pricks or feinting motions before her eyes. Sometimes she retained her urine, again wet and soiled the bed. Often there was marked catalepsy, and the retention of very awkward positions. As a rule she was quite stiff, offering passive resistance towards any interference. She had to be tube-fed at first. Later she was spoon-fed, and then would swallow, in spite of the fact that during the interval between her feeding she would let saliva collect in her mouth. For a time she had a tendency to hold one leg out of bed, and when it was put back would stick the other out. Sometimes she walked of her own accord to the toilet chair, but on one occasion wet the floor before she got there. During the first month after admission, this stupor was interrupted for two short periods by a little freer action: she walked to a chair, sat down, smiled a little, fanned herself very naturally when a fan was given to her, though even then did not speak. There was, as a rule, no emotional reaction, but after some months she several times wept when her mother came, though without speaking. Once when taken to the tub she yelled. Her _physical condition_ during this stupor was as follows: She menstruated freely on admission, then not again until she was well. Several times she had rises of temperature to 102° or 103° with a high pulse and respiration; again a respiration of 40, with but slight rise of temperature, though the pulse had a tendency to go to 130 and over. She was apt to show marked skin hyperæmia wherever touched. With the fever there was found a leucocytosis of from 11,900 to 15,000, with marked increase of polynuclear leucocytes (89%). She got very emaciated, so that four months after admission she weighed 68 lbs. (height 5′ 2″). 2. About five months after admission she was often seen smiling, and again weeping, and she began to talk a little to the nurses, though not to the doctors. She also began to eat excessively of her own accord, and rapidly gained weight, so that by January she weighed 98½ lbs., a gain of 30 lbs. in two months. Yet she continued to be sluggish.
